Background: The ability to adapt and habituate based on prior experiences is important for human movement control, fall prevention and for the ability to enhance performance during various human activities. However, little is known about the ability for the elderly to adapt to balance perturbations in the lateral direction. Objective: To determine whether adaptation, i.e., the ability to adjust po
BACKGROUND AND AIMS: The optimal position for pH electrode placement in the diagnosis of gastroesophageal reflux disease (GERD) is unknown. The aim of this study was to evaluate the discriminatory power of targeted pH recording immediately above the squamocolumnar junction (SCJ) and to compare the results with those obtained by simultaneous recording at the conventional level for pH monitoring. SU
The main objective of this thesis was to identify methods for the detection of ß-lactam resistance in staphylococci, bacteria often causing nosocomial infections. Detection of ß-lactam resistance in these species is difficult due to strong regulation of genes encoding for the two main resistance mechanisms, ß-lactamase production and the penicillin-binding protein (PBP) 2?. ß-lactamase has high af
The transport of fallout-90Sr has been investigated in the food-chain: Lichen-reindeer-man during 1961-1969. The maximum levels which occurred in lichen during 1963-1965 were about 13 nCi/kg dry wt. The90Sr-level in the lichen-carpet decreased to about 5 nCi/kg dry wt. in 1967-1969. The effective half-time of 90Sr in the lichen-carpet was estimated to be 2.5 ± 0.8 a. The vertical distribution of90
Samhällsreformer och utvecklingen inom den svenska offentliga sektorn har omformat förutsättningarna för socionomyrket och andra professioner samt förändrat socionomernas arbetsområde. Jag har använt begreppet karriär för att undersöka förändringar inom socionomprofessionen, eftersom det ger ett perspektiv för att belysa stabilitet och förändring samt kan fånga både externa och interna krafter i pSocietal reforms and development within the Swedish public sector have reframed the prerequisites for social workers, and other professions, and changed the area of work practice. I have used the career concept in order to investigate professional change because it provides a conceptual lens to illuminate stability and change and it captures both external and internal professional processes. To ma
Objective: Falls and related injuries are known to be the major health problem leading to disability and mortality among older adults. Identification and management of fall risks aimed to prevent falling is considered to be essential. The aim of this study was to develop a mobile application for screening and management of fall risks based for older adults. Method and materials: First, we determin
In children with single ventricle physiology, increased pulmonary vascular resistance may impede surgical progression or result in failing single ventricle physiology. The use of pulmonary vasodilators has been suggested as a potential therapy. However, knowledge on indication, dosage, and effect is limited. A retrospective case notes review of all (n = 36) children with single ventricle physiolog
Cold sensitivity is common following nerve injuries in the upper extremity, but is less well studied in carpal tunnel syndrome (CTS). We investigated cold sensitivity in CTS and its effects on surgical outcome. A search of the Swedish National Registry for Hand Surgery (HAKIR) for open carpal tunnel releases (OCTR) from 2010–2016 identified 10,746 cases. Symptom severity questionnaires (HQ-8; HAKI
Tropical evergreen forests contribute an important part to the interannual variability (IAV) of the global terrestrial gross primary productivity (GPP). Due to its year-round growing-season, high minimum carbon uptake (GPPmin) and dry season greening-up, the key processes driving the GPP variability across seasonal to interannual scale are still in debate. Here, we analyzed the time-series of FLUX
The emissions of 137Cs into the environment from the nuclear accidents in Chernobyl in 1986 and Fukushima in 2011 led to the need to decontaminate large areas to avert radiation doses to the population in the affected areas. To be able to perform cost-effective and sustainable remediation, knowledge is needed about how radiation doses can be minimized through optimized interventions such that the
Background European forests have a long record of management. However, the diversity of the current forest management across nations, tree species and owners, is hardly understood. Often when trying to simulate future forest resources under alternative futures, simply the yield table style of harvesting is applied. It is now crucially important to come to grips with actual forest management, now t
Intraocular lens (IOL) exchange after cataract surgery is unusual but may be associated with suboptimal visual outcome. The incidence of IOL exchange has not been consistently estimated. Such information is invaluable when counseling patients prior to cataract surgery. We examined the incidence of, and indications and risk factors for, IOL exchange after cataract surgery. We also assessed visual o
Granulosa and theca cell tumors of the ovary account for 2-3% of ovarian malignancies. This study includes 54 patients with the diagnosis of granulosa cell tumors of the ovary treated between 1953 and 1987. Median age at diagnosis was 57 (27-83) years. The lesions were staged according to FIGO. The number of patients in various stages was IA, 41; IB, 3; IC, 3; IIB, 6; and III, 1. Median tumor size
BACKGROUND: The aim of this paper is to investigate the causality of the inverse association between cigarette smoking and Parkinson's disease (PD). The main suggested alternatives include a delaying effect of smoking, reverse causality or an unmeasured confounding related to a low-risk-taking personality trait. METHODS: A total of 715 incident PD cases were ascertained in a cohort of 220 494 indi
Nature-based adaptation planning is a challenging endeavor, not least because it requires transdisciplinary approaches to unite different actors' efforts and capacities. However, empirical knowledge on associated governance processes is scarce and fragmented. Against this background, this paper examines the integration of nature-based approaches for climate change adaptation into municipalities’ d
The ontogenetic development of size heterogeneity and aggression was monitored in commercial culture tanks of yellowtail kingfish (Seriola lalandi Valenciennes). Size heterogeneity increased substantially with the introduction of Artemia as a food source at 12 days post-hatch (DPH), and was correlated with the appearance of aiming behaviour, a precursor to more direct aggressive interactions. Chas
The aim of this research was to analyze the effects and the modes of action of elemental sulfur (So) in bioluminescence and respiration of Vibrio fischeri cells and the enzymes crude luciferase, pure catalase, and alcohol dehydrogenase (ADH). Metallic copper removed sulfur and reduced the toxicity of acetone extracts of sediment samples analyzed in the bioluminescence test. The sulfur inhibition o
This is a study on the recovery and recycling of copolymer in aqueous two-phase systems containing random copolymers of ethylene oxide (EO) and propylene oxide (PO). The random copolymers separate from water solution when heated above the lower critical solution temperature (LCST). The primary phase systems were composed of EOPO copolymer and hydroxypropyl or hydroxyethyl starch. After phase separ
Microchip immobilized enzyme reactors (mu IMERs) with immobilized endoglucanases were applied for the hydrolysis of methyl cellulose (MC). MCs of various molecular weights were hydrolyzed using two mu IMERs containing immobilized celloendoglucanase Cel 5A from Bacillus agaradhaerens (BaCel 5A) connected in series. Hydrolysis by the mu IMER could be confirmed from the average molar masses and molar
